some kunena ext links yield 404 error - Forums Task Topic P 2 Id 1147

I'm sorry to be such a pain about it.

Just now, I did a fresh install of joomla, acesef and kunena and the problem still exists for me.

Ah, that was the problem!  It works absolutely perfect now!  Thank you so much.  This REALLY saved me.

Unfortunately, I found the same problem in hwdvideoshare ext   Again, it seems to happen with #, but I disabled the meta there too and it also works perfect.

Sure, I have been making a note the entire time in the event you asked.  The problem is at some point URLs without those special characters were also returning 404, however, it's possible those times I didn't clear browsers, URL, and joomla cache each time.

The special characters I have documented with the problem are:

! , # ? ' " : ;

It should also be noted in the case of the colon.  A 404 page was only returned some of the time and not every time.
